Since my wife is a runner and currently taking a long break from running, when she makes a come back around August, we will be working on her running in this manner rather than as a heel striker.

@ ADAM.

I've shared it elsewhere on the forum here, but if you're trying to change technique, this series is really in-depth and thoughtful: http://www.sportsscientists.com/2008/01/running-technique.html (http://www.sportsscientists.com/2008/01/running-technique.html).

Thanks! Will definitely give it a read.

for brucelee, he says marathonners all go heel->toe:

correctly running humans don't jam the heel, it's mid foot.. a slight graze of heel can make contact, but it's not going to be that leg extended jamming into the ground that you always see from people who run in jogging shoes their whole life.

With respect to the first vid in your last post:

"The scientists set up a high speed camera...at the 15km mark of the race, and captured most of the runners coming through. In total, they were able to observe the foot strike of 248 men and 35 women, and characterize them...

...the finding is the following:

    * The vast majority (75%) of the elite runners land on the heel"

http://www.sportsscientists.com/2008/04/running-technique-footstrike.html (http://www.sportsscientists.com/2008/04/running-technique-footstrike.html)

In short, as many people in the barefooting movement are smug morons as in Paleo or Crossfit. Not to denigrate barefoot running by comparing it to the latter two, and I believe in barefoot running in principle. But the point stands that it's a movement and therefore many of its most enthusiastic supporters are just zealots.

right, well as far as landing on the heel goes, i guess it can be classified a few different ways.. most of those guys who do 'land on heel' aren't applying much force in that position, it seems as if they are just grazing the heel on the ground and impacting more on mid foot.

edit: i can't imagine forefoot running a marathon, thats insane that some people can do that..

i run a little too much on my toes..well i am more of a sprinter than distance runner now..so i do not even fell my heel when i sprint...is this bad or wrong? i have seen that video of asafa in slow mo and i think that maybe i should land a little bit flatter but still on the ball of my feet, then plantar flex

well when it comes to sprinting, you're definitely going to be on your toes alot when you have forward lean, ie acceleration.. once you reach max V, you should be pawing the ground with mid-foot..

as far as distance running goes, many schools of thought on that one.. i'm glad i switched to mid-foot for distance but it's definitely taken a long time to get used to, and even now i'm still not 100% adapted to it.. i will be one day i know that for sure.. but i definitely feel more springy running distance on mid-foot.. that spring dies as i fatigue in the calfs though.. so once my calfs are stronger, i'll have that spring for the entire run... i don't like heel->toe for distance, i mean, if you ran barefoot you wouldn't be running heel->toe.. i'm talking a major heel strike here though, not just a light brushing of the heel while in flight, i'm talking about a weightbearing strike.. that shit is not good imo.

peace!

yea but don't i wanna get more push from my calf, so i am gonna work on plantar flex, hit ground with ball of foot but with a more parallel foot 2 ground, and then push off the ball of my foot...i am saying that i'm on my toes almos the entire time...my teammates say it looks like I'm jumping when i run...alot say i prance when i'm jogging lol
